1* Dialog DA9055 Power Management Integrated Circuit (PMIC)
2
3DA9055 consists of a large and varied group of sub-devices (I2C Only):
4
5Device			 Supply Names	 Description
6------			 ------------	 -----------
7da9055-gpio		:		: GPIOs
8da9055-regulator	:		: Regulators
9da9055-onkey		:		: On key
10da9055-rtc		:		: RTC
11da9055-hwmon		:		: ADC
12da9055-watchdog		:		: Watchdog
13
14The CODEC device in DA9055 has a separate, configurable I2C address and so
15is instantiated separately from the PMIC.

22Required properties:
23- compatible : Should be "dlg,da9055-pmic"
24- reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
25- interrupt-parent: Specifies the phandle of the interrupt controller to which
26  the IRQs from da9055 are delivered to.
27- interrupts: IRQ line info for da9055 chip.
28- interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
29- #interrupt-cells: Should be 1, is the local IRQ number for da9055.
30
31Sub-nodes:
32- regulators : Contain the regulator nodes. The DA9055 regulators are
33  bound using their names as listed below:
34
35    buck1     : regulator BUCK1
36    buck2     : regulator BUCK2
37    ldo1      : regulator LDO1
38    ldo2      : regulator LDO2
39    ldo3      : regulator LDO3
40    ldo4      : regulator LDO4
41    ldo5      : regulator LDO5
42    ldo6      : regulator LDO6
